[PATCH v3 0/7] PinePhone BT audio bringup

This series uses the additional DAIs added to the sun8i-codec driver to
add hardware routing for BT SCO (headset) audio on the PinePhone.

The BT audio connection is represented by the "dummy" bt-sco codec. The
connection to the Quectel EG-25G modem via AIF2 works as well, but I do
not include it here because there is no appropriate codec driver in
tree. We have been using an out-of-tree "dummy" codec driver for the
modem similar to bt-sco, and I'm not sure if such a driver would be
desired upstream.

Changes from v2:
  - Also accept #sound-dai-cells in the binding. Since dt-core.yaml
    already sets the type of this property, it is not possible to use
    oneOf, nor make a specific value deprecated.

Changes from v1:
  - Fixed DT binding example to follow new binding
